A Notice of Violation/Intent to Issue Civil Penalty is being issued for the noted violations of North Carolina General

Office as soon as possible, not to exceed 24 hours, from first knowledge of any non-compliance at
the facility including limit violations, bypasses of, or failure of a treatment unit. A written report may

potential problems due to planned maintenance activities, taking units off-line, etc.
Additionally, and if you have not already done so, you may wish to consider registering to use the Division's new
e -DMR system for the completion and electronic submittal of monthly Discharge Monitoring Reports (DMRs).
